A Study Measuring Effect of LY2140023 (Pomaglumetad Methionil) on Electrocardiographs in Participants With Schizophrenia

NCT ID: NCT01606436

Last Updated: 2023-04-03

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 86 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2012-06-30
• Study Completion Date: 2012-09-30

Brief Summary

This study determined if a single dose of LY2140023 (pomaglumetad methionil) affects the electrical activity in the heart in participants with schizophrenia. This study also helped determine how a single high dose of LY2140023 is tolerated by participants.

Detailed Description

The primary objective of this study was to determine that a single supratherapeutic dose of LY2140023 does not differ from placebo in the mean change from baseline in 12-lead electrocardiogram (ECG) QT interval measurements, such that the upper bound of the 2-sided 90% confidence interval (CI) for the greatest time-matched mean effect is <10 ms in subjects with schizophrenia. The secondary objective was to further evaluate the tolerability of a supratherapeutic single dose of LY2140023 monohydrate.

Male or female subjects diagnosed with schizophrenia and aged between 18 and 65 years, inclusive, who had not been hospitalized for psychiatric illness for at least 12 weeks prior to Day 1 of the lead-in period, and who had a Clinical Global Impression - Severity scale score of <4 were included in the study.
